Easter Bay provides a natural geographical and meteorological barrier between the warm, arid desert region of Tierra Robada and the moist, cool area surrounding San Fierro. Occasionally, however, the dust storms from Tierra Robada will cross the bay and influence the weather patterns in San Fierro.

Toreno convinces Carl to do his dirty work, with Sweet's continued safety as collateral for Carl's loyalty. One of the tasks Carl is asked to perform is to steal a Hydra from an aircraft carrier in Easter Basin. Toreno deposits Carl opposite Easter Basin in Red County, near The Panopticon. It is then up to Carl to make his way across Easter Bay and around the main tarmac of Easter Bay Airport in order to reach Easter Basin Naval Station and steal the jet.
